고칼슘 소각재 치환율에 따른 비소성 시멘트 모르타르의 특성 = Properties of Non-Sintered Cement Mortar with High-Calcium Fly Ash

다국어 초록 (Multilingual Abstract)

In this study, certain portions of non-sintered cement mortar were replaced with industrial subsidiary high-calcium flyash (HCFA) and fly ash (FA) to reduce CO2 emissions. After fixing the ratio of FA to 30%, 20%, 30%, 40% of HCFAwas added to produce mixed cement. We conducted a through-flow test, strength experiment, absorption test, neutralizationtest, XRD analysis, and SEM scanning to identify the physical characteristics of HCFA and determine its applicabilityas cement. Our results showed that a higher proportion of HCFA in non-sintered cement mortar resulted in higher W/Band absorption rates and lower strength and neutralization resistance. Our findings confirm that non-sintered cement mortaris applicable in secondary PC product areas where rebars are not used and where long-term stability or high strength isnot required (particularly at the beginning of construction).
